HELP! for loops and document.write problem

Hello, I have a problem with the following code!
I want to use it so that customers check a checkbox under each photo they want, in a photo gallery, and when they finish, they can click and the photos they checked appear using document.write in a new page!
The problem I have is that when the script finds the first image, it uses document.write, shows only the first image it finds and then ends the foor loop!
How can I code it so that it finds all the photos first and then shows them in the new page!
Here is the sample code, sorry for my bad English and thanks for your time!
--------------------------------------------------------------------------

<script type="text/javascript">
function findphotos(test){
for (i=0; i<document.test.checkgroup.length; i++){
if (document.test.checkgroup[i].checked==true){
document.write('<img src="'+i+'.jpg">');
}
}
}
</script>

<form name="test">
<input type="checkbox" name="checkgroup" />
<input type="checkbox" name="checkgroup" />
<input type="checkbox" name="checkgroup" />
</form>
<h1 onclick="javascript:findphotos(test)">Find</h1>

Each call to document.write() erases the page including the script. So it only works once.

document.write statements must be run before the page finishes loading. Any document.write statement that runs after the page finishes loading will create a new page and overwrite all of the content of the current page. So document.write is at best really only useful to write the original content of your page. It cannot be used to update the content of your page after that page has loaded.

If you wish to pass variables to a new page you must use a query string or a cookie.

All advice is supplied packaged by intellectual weight, and not by volume. Contents may settle slightly in transit.

Thanx for your replay! If you have any reference about doing that I would appreciate it! Or if there is any other way to write at the same page instead of using document.write! Thanx again for your time!
